What is the difference between OLA and technical service catalog? can we just implement one of them?

OLA is an internal agreement (two different parts, e.g. departments, of the same organization) where you define activities in scope with related parameters, e.g. response time). More about OLA in this document "SLAs, OLAs and UCs in ITIL and ISO 20000“ https://advisera.com/20000academy/knowledgebase/slas-olas-ucs-itil-iso-20000/
OLA can be a formal document but can be also e.g. ticket forwarded to another department.
The technical service catalogue is part of the Service catalogue and describes the service in technical parameters. More about Service catalogue in the article "Service Catalogue – a window to the world“ https://advisera.com/20000academy/blog/2013/03/19/service-catalogue-window-world/ and "Service Catalogue – Defining the service“ https://advisera.com/20000academy/blog/2014/03/11/service-catalogue-defining-service/ or in this free webinar " ITIL Service Catalogue from scratch“ https://advisera.com/20000academy/webinar/itil-service-catalogue-from-scratch-free-webinar-on-demand/
